upnmthesis is a LaTeX class for authoring theses that fulfill formatting specifications required by Universiti Pertahanan Nasional Malaysia (UPNM). This class and template was commissioned by the university's Centre of Graduate Studies in April, 2016, for both undergraduate and postgraduate theses. A sample file sample-thesis.tex, as well as relevant sample chapters, are included in the package. upnmthesis is available as a template on Overleaf which I recommend you modify for your own thesis write-up. (You can rename it, but I'll stick with the file name sample-thesis.tex throughout this guide.) The latest version of this template can also be downloaded from my website.
A variant and a combination of Hering's and Zöllner's illusion. The red grid is completely straight all the time.
